B What material is best suited for making Chladni figures?

  1. Jun 15, 2016 #1
    Hello! For an assignment I am planning to investigate the natural frequency modes of a circular membrane using the "Chladni technique". Usually, these Chladni plates are made out of metal, allowing them to be firm but still quite flexible. For my assignment I am planning on using a thin layer of plexiglass, however when I have a look around online I cannot find anyone else that have tried this and so I am a bit unsure whether this will work out.

    Would using plexiglass be a good idea?

    Should work, waves travel through all solids. It is an interesting experiment though. You may get a different response based on the material used due to the difference in in the speed of sound in the material. Try both!
